Ideas for Over Winter Workshop Space?

I have some large, temperature sensitive projects I’ll be doing on my 22 Cruiser after this season. I live in RI, and have only backyard outdoor space.

Indoor boat storage is at quite a premium up this way, so I’m looking for out of the box ideas. Perhaps an RV facility, a private barn (insurance if fire?), high door storage unit (do those exist?), etc..

My concern is that I won’t have any financially reasonable options, and that I might end up paying more to do the projects myself after parts, labor, and storage, than if I just paid a shop to do it.

I’m not shying away from the work, but my garden comes to mind: bought the wood, built the beds, bought the dirt etc., the plants, the time, and it’s all of a sudden $50 each tomato lol

Thank you for your suggestions.

PS- My town does not “allow” carport style storage tents/sheds.

Edit: My mistake. This town allows carports. It was my last one that did not. I would, however, need a setback variance with town zoning board and neighbor approval. Too late to edit the original post. That said, I’d still prefer a properly climate controlled option, and one that i can guarantee vs relying on approvals. Open to options.
